Exactly the same as Citrix
As an ex-Citrix person, this was (is) their exact playbook too. Stop all support for perpetual licensing through ending Support, and force everyone on subscriptions. They'll dress it up as being a technical requirement (we need to continually verify your machines are compliant!) but it's all about that lovely on-going subscriber revenue feed.
And now with their on-line licensing server requirement, you can't just shut up shop and keep everything as it works today. You need to have a internet-exposed connection out to verify your license files every 3 months, or else... Funnily enough, that license data will also be continually reporting precious usage information to help the next sales cycle.
